Patented Dec. 22, 194-2 RELAY SWITCH STRUCTURE Louis W. Gensburg, Qhicago, Ill., assignor to Genco Mfg. (30., Chicago, llll, a copartnership consisting of Louis W. Gcnsburg, David Gensburg,

and Myer Gensburg Application September 21, 1940, Serial No. 357,766

2 Claims.

This invention relates to certain novel improvements in gang switches, and more particularly to mechanism for simultaneously operating the switches, and has for its principal object the provision of an improved structure of this character which will be highly efiicient in use and economical in manufacture.

One of the many objects of this invention is the combination and arrangement of parts such as will eliminate the necessity of fine adjustment between the contact points of each switch, thereby assuring positive engagement between such contacts.

Another object of the invention is the combination and arrangement of parts such as will afiord simple, expeditious and convenient assembly.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing showing the preferred form of construction, and in which:

Fig. l. is a perspective View of the gang switch embodying the invention;

Fig. 2 is a vertical cross sectional detail of the same; and

Fig. 3 is a view taken substantially on line 33 of Fig. 1.

The particular use to which my invention is applied is immaterial. In the present form, the invention may be used to control any type of electric circuit wherein it is necessary to employ gang switches operated simultaneously through electromagnetic means in the form of a magnetic relay.

In the preferred form of construction, a supporting structure is indicated at Hi and from this structure is supported. as at H, one or more electromagnetic relays l2 including a spring-controlled armature 23. Supported from. this structure [El is a plurality of switch units M, each constituting a gang of switches l5 including cooperating contact points Pivotally mounted on the top plate ll of the structure NJ, as at It, is depending arm is urged in one direction by means of a spring 20. Extending laterally as at 2! from this arm H3, is a finger 22 having a plurality of spaced slots formed therein. Projecting through these slots are the spring leaves 24 of the switch structures 95.

Pivotally supported from the top plate ll, as at 25, is a Ushaped resetting bracket the bight portion 2i of which is adapted under certain conditions to engage the depending arm 19,

Secured to the armature I3 is a latch finger 28 which normally engages the depending arm 19, releasably retaining the arm it in the position shown in 2, against the action of the spring 2Q, thereby maintaining certain of the contacts it of the gang switch I l separated and others in contact with respect to each other.

The arrangement is such that when the coil of the electromagnetic relay i2 becomes energized, the armature it will be attracted to the core 13' thereof, releasing the latch 2? from the arm l9, permitting the arm it to be pivoted in a clockwise direction by the spring iii to bring certain of the contacts iii into engagement and to disengage other contacts, such as it, of the gang switch H. To reset the switch leaves in the position shown in Fig. 2, the resetting bar 25 is pivoted through an instrumentality (not shown) to bear the bight portion 21 thereof against the depending arm H! to JZ VQt the same against the spring 26 in an anticlockwise direction, thus permitting the latch 28, by the action of the latch spring 25), to assume latched position with respect to the arm l9.

From the description herein taken in connection with the accompanying drawing, it is obvious that I provide a gang switch which assures positive operation, is simple in structure, and consists of a combination and arrangement of parts which afford economical and expeditious assembly.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In a switch structure of the gang type, a main body, a plurality of leaf switches arranged on said main body, certain leaves of said leaf switches extending beyond the other of said leaves thereof, lever means pivotally mounted on said main body, a lateral extension on said lever means for movement therewith and having slots formed therein, each of said certain leaves having their respective free ends disposed through a separate one of said slots to render said certain leaves moveable with the lever means, spring means arranged between said main body and said lever means and adapted to urge the latter and said certain leaves into one position, latch means for said lever means and adapted to retain the latter and said certain leaves in a position opposite to said first named position against the action of said spring means, means mounted on the main body for releasing said latch means from retaining engagement with said lever means, and a reset bar pivotally supported on said main body and adapted to engage said lever means for urging the latter into latched relation with respect to said latch means.

2. In a switch structure of the gang type including a body supporting a plurality of leaf switches with certain leaves of said switches extending beyond the remainder of the leaves there-- of, a lever pivotally mounted on said body and carrying a switch engaging extension having operative engagement with each of said certain leaves to render the latter moveable with said lever means, spring means between said body and lever means for urging the latter into one position, latch means for said lever means and adapted normally to latchirigly retain the latter in a different position to that aforementioned, means on said body for urging said latch means out of latching relation with respect to said lever means, and a reset bar pivotally arranged on said body and adapted to engage said lever means to urge the latter into latched engagement with said latch means.
